Abstract
An image forming apparatus has a backup memory for storing data on image forming in a memory. When the power supply of the apparatus is turned off due to a trouble, a controller reproduces a status just before the power supply is turned off according to the data stored in the backup device if a predetermined time passes after the power supply is turned on again. However, new image forming is started if a preparation operation for new image forming is detected within the predetermined time. Further, if the power supply is turned off while a document is read, the controller reproduces the status just before the power supply is turned off when the power supply is turned on again.
